Understanding the Visible Colors of Light

When it comes to the visible colors of light, many people are familiar with the well-known acronym ROYGBIV, which stands for red, orange, yellow, green, blue, indigo, and violet. These colors make up the spectrum of visible light that our eyes can perceive. But have you ever wondered about the energy levels associated with each of these colors?

In physics, the energy of light is directly related to its wavelength. Generally, light with shorter wavelengths has higher energy, while light with longer wavelengths has lower energy. With this in mind, we can determine the correct order of increasing energy for the visible colors of light.

Which of the following arrangements of the visible colors of light is in the correct order of increasing energy?

Group of answer choices

1. red, orange, yellow, green, blue, indigo, violet

2. violet, indigo, blue, green, yellow, orange, red

3. red, yellow, orange, green, blue, indigo, violet

4. violet, indigo, green, blue, yellow, orange, red

Based on the wavelength-energy relationship of light, we can determine that the correct order of increasing energy for the visible colors of light is actually:

Answer:

2. violet, indigo, blue, green, yellow, orange, red

This means that violet has the highest energy among the visible colors, while red has the lowest energy. So next time you see a rainbow or a spectrum of colors, remember that each color represents a different energy level of light!
